130031-97-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 130031-97-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,0,0,3 and 1 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 130031-97:
(8*1)+(7*3)+(6*0)+(5*0)+(4*3)+(3*1)+(2*9)+(1*7)=69
69 % 10 = 9
So 130031-97-9 is a valid CAS Registry Number.

Synthesis of 1-Phenyl-1,2- and 4-Phenyl-1,5-dihydropentalenes
Griesbeck, Axel G.
, p. 403 - 405 (2007/10/02)
An efficient one-pot synthesis of 3-substituted 1-phenyl-1,2-dihydropentalenes from α,β-unsaturated ketones is described.These compounds can be rearranged to their 1,5-dihydro isomers using different methods such as acid catalysis and vacuum-flash thermol
